Can standard redox potential of the Pd(II) to Pd (0) be altered due to palladium ligand complex? Myself too think this is possible. But I wanted to find some proofs from literature and further explanation from community. Thanks.
I can say Yes the formal redox potential of Pd(II) Pd(0) redox couple can be altered on complexation. This effcet is called complexation effect on redox potential of Transition metal ions and can be explained as :
A particular ligand stabilizes the two oxidation States in a transition metal redox couple differently this changes the tendency of the metal to get oxidized or reduced compared to its tendency in absence of ligand. Depending upon whether higher or lower oxidation state is stabilized the redox potential changes differently in case of lower oxidation state stabilization the reduction potential increases and in case of higher oxidation state stabilization the redox potential gets decreased. In this particular redox couple ligands which stabilize Pd(II) more than pd(0) will lower the reduction potential and ligands which stabilize Pd(0) more than Pd(II) will accordingly raise the reduction potential This concept is useful for a variety of novel applications see the attached papers. Hope i could understand your question and my answer was any helpful.
Yes You have understand my question perfectly, this is the exact answer for my question. Thank you very much for you and also to the researchgate which make such a great platform to connect experts together. A very valuable answer which save me a lot of time. Thanks again.
yes. Complex accepting charge can decrease the potential.
